Rating Newest Oldest. Best Answer: Oil will definitely cause the clutch to grab and chatter. Other causes involve the flywheel and pressure plate surfaces and uneven apply pressure from the pressure plate.
Differential area relief valves must have seals to prevent leakage. Most counterbalance valves have one to three dynamic seals in them, which introduce friction, resulting in hysteresis. Friction caused by the dynamic seals makes the valve stick, causing an overshoot in pressure. The counterbalance valve then shifts to correct itself and undershoots. The result of hysteresis is bounce, loud chatter, or high-pitch squealing. Sometimes this chatter is caused by the design of the cylinder, not the counterbalance valve. The more dynamic seals in the counterbalance valve, the greater the hysteresis will be. When caused by the cylinder, no counterbalance valve in the world can reduce this chatter. Treat symptoms or the cause. Many counterbalance valves offer options to treat the symptoms. Most counterbalance valves come with a pilot ratio anywhere from 1.75:1 to 12.0:1.
